Description

Technical Field

[0001] The utility model relates to the technical field of waterproof components, in particular to a prefabricated roof inner corner waterproof protection component. Background Art

[0002] The high-rise residential building is a shear wall structure, and the roof of the high-rise residential building is an inverted non-walkable roof. The roof waterproofing material uses a self-adhesive polymer membrane. Due to functional and decorative requirements, the roof is arranged with pipes, parapets and other structures. These structures are perpendicular to the building roof. According to the design requirements of the waterproof layer, the waterproofing needs to extend to the facades of these structures to meet the flashing height.

[0003] At present, the commonly used method for waterproofing the roof corners is: cement mortar + mesh plastering protection. Due to the different materials, it is difficult to bond the waterproofing with the mortar, which often causes large-scale hollowing and cracking. The waterproofing protection effect of the flooding area is ineffective, resulting in waterproofing aging, cracking, and water leakage.

[0004] Therefore, a prefabricated roof inner corner waterproof protection component is proposed. Utility Model Content

[0005] The utility model aims to provide a prefabricated roof internal corner waterproof protection component to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a prefabricated roof internal corner waterproof protection component, including a waterproof membrane laid on the roof internal corner, a plurality of prefabricated components arranged according to the roof internal corner are built at the roof internal corner, the prefabricated components are bonded by cement mortar, the prefabricated component includes a fixing surface in contact with two side walls forming the roof angle, an inclined surface is arranged between the fixing surfaces, and mortar is filled between the inclined surface and the waterproof membrane.

[0007] According to the above technical solution, the side of the prefabricated component away from the inclined surface is arc-shaped.

[0008] According to the above technical solution, arc-shaped steel bars extending in the same direction along the arc-shaped surface are arranged inside the prefabricated component.

[0009] Compared with the prior art, the beneficial effect achieved by the utility model is as follows: the utility model forms an aesthetically pleasing and effective waterproof protective layer by applying mortar on the waterproof membrane, installing the prefabricated components after applying the mortar, pressing the waterproof membrane to make it tight, and then connecting it with the large surface waterproof protective layer of the roof through concrete pouring.

[0010] Prefabricated components can exert horizontal pressure on the water-shedding of the coiled material, ensuring that the coiled material fits tightly with the base layer, which can effectively prevent the coiled material from bulging and peeling off. At the same time, there is no need to consider the hollowing, cracking and water seepage of the protective layer. BRIEF DESCRIPTION OF THE DRAWINGS
